LIQUID SOAP DISPENSING- DEVICE Filed Nov. 1, 1928 fatentecl Aug. 26, 1930 barren STATES PATENT critics AXEL REINHOLD HESSELBLAD, F LIDINGO, SWEDEN LIQUID-SOAP-DISYENSING DEVICE Application filed November 1, 1928, Serial No. 316,483, and in Sweden November 10, 1927.

This invention has reference to certain improvements in that class of apparatus for distributing liquid soap or the like in measured quantities which comprise a pivotal receptacle in which a central tubular valve chamber is arranged, said tubular valve chamber being in connection with the interior of the receptacle and also with a nozzle of the receptacle and having a valve body movable in the tubular valve chamber and adapted to fall down and close the nozzle when the receptacle is tilted over. i

The object of the invention is to facilitate the adjustment ofthe valve chamber in relation to the receptacle in such a manner that an opening in the valve chamber through which opening the liquid of the receptacle enters the valve chamber, will be located upward, when the receptacle is tilted over. Hitherto, the valve chamber has been attached to the receptacle in'such a manner that a sleeve firmly connected to the valve chamber, has

been screwed down as far as it goes on an annular threaded socket mounted on a neck of the upper part of the receptacle, the valve chamber extending into the receptacle through said neck. Thereby the location of the opening in the valve chamber has been dependent upon the position of the socket on Q the receptacle. As said socket is attached (by means of cement or the like) to the receptacle while the valve chamber or the like is wholly separated from the socket it has been very troublesome to bring the socket in such exact position on the receptacle necessary for getting the proper location of the valve chamber, that is to say, so that the opening therein will be turned upward, when the receptacle is tilted over. This inconvenience is avoided by the present invention.

The nature of the invention is explained below and by the accompanying drawin wherein Figure 1 is a vertical section through the apparatus, and Figure 2 is a sectional View of a detail.

The receptacle 1 is mounted. on two pivots so as to be capable of tilting, one of said pivots appearing in the drawing and having the reference 2. 3 is the valve chamber, 4

sleeve.

the valve body, and 5 the nozzle which isremovable and serves as a valve seat. The opening of the valve chamber has the shape of a longitudinal cranny 6 which will be turned upward when the receptacle is tilted in the direction of the arrow. The valve chamber is connected to a cap 8 screwed on the annular socket 9 previously referred to.

According to the invention, this cap is pro vided with an adjustable look by means of which the valve chamber is fixed in its proper position with regard to the opening 6. The lock consists of a screw 10, but itmay of course consist of another member. This screw traversing the side of the cap, is introduced into its hole from the inside of the cap but is attainable from the outside, where it, as usual, is provided with for instance a chisel slot or a square head of the kind which is usually used in looks for lavatories of railway compartments or the like.v In order to be able to fix the capfirmly in desired position, the resting surface of the screw for the socket has an area larger than the cross-section of the screw. When the screw 10 has been wholly screwed out the head is on a level with the upper edge of the screw sleeve. When it has been tightened, that is to say, when the cap 8 with the valve chamber 3 has been locked in position on thereceptacle l, the headis located beneath the level of the As the cap 8 internally is higher than the threaded socket 9 attached tothe receptacle, thecap 8 with the valve chamber 3 after being screwed on, cannot rest against the socket 9, and owing to the lock 10 of'the cap, the latter need not be brought to rest against the outer side of the receptacle. when the valve chamber 3 is locked in adjusted position in the receptacle with regard to the opening 6 which also prevents the cap from being stuck tofthe socket. Another advantage ofthe square screw head is that the removing of the valve chamberby way of mischief as often occurs is rendered more difiicult. i

The devicefor locking the valve chamber in adjusted position in the receptacle may alsobe made in such a mannerv that a nonthreaded part (wear edge) remains at the top of the socket 9, said part being not engaged by the threads of the cap. In such case the screw 10 is so arranged, that it can- 5 not be screwed out so far that its inner end may enter the threads of the socket 9 when screwing on the cap, but strikes against the abutting edge formed by the threaded part. Thereby the screw and the abutting edge but not the upper edge of the socket, determine the deep-position into which the cap may be screwed down on the socket.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device for dispensing liquid soap or the like in measured quantities comprising a tiltable receptacle having a neck and a mouth at the upper part thereof, a collar anchored to the neck, a cap engaged with the collar, a valve chamber carried centrally of the cap and suspended within the receptacle and provided with a longitudinal slot and also having a soap outlet at the top, a valve member in the chamber and means adjustably mounted in the cap for frictionally engaging the outer surface of the collar whereby to anchor the cap to the collar and to regulate the position of the slot. 0 2. A device for dispensing liquid soap or the like in measured quantities comprising a tiltab e receptacle having a neck and a mouth at the upper part thereof, an exteriorly threaded collar anchored to the outer surface of the neck, an interiorly threaded cap engaged with the collar and provided with a central aperture, a valve chamber carried by and depending from the cap about the opening therein and provided with a longitudinal slot to allow liquid from the receptacle to pass into the chamber, a combined nozzle and valve seat element mlounted in the opening in the cap, a valve member within the valve chamber for closing the nozzle at times, a screw mounted in and carried by the cap for engagement with the threaded collar so as to anchor the cap and consequently the valve chamber substantially as and for the purpose set forth.

x'! 3. A dispensing device as claimed in claim 2, wherein the screw is provided on its inner end with an enlarged flat head while the lateral opening in the cap for the screw is enlarged at its inner end to leave a recess for accommodating the head, and the screw being insertable from the inside of the cap.

4. A dispensing device as claimed in claim 2 wherein the threaded part of the cap is longer than the neck of the receptacle so that I) the cap when screwed on the collar will be spaced from the outer edge of the collar.

5. A dispensing device as claimed in claim 2 wherein the extreme outer portion of the collar is reduced and provided with a 3 smooth surface, the screw being adapted to AXEL REINHOLD HESSELBLAD.
